I've read through some of the old threads here and found that some people have gotten help for oily skin by taking vitamin B5. I have a few questions about it, and hope someone will be able to provide some input. My info: I'm a 35 year old female, very oily skin (only on face), don't really have acne problems but do have a few blackheads. My biggest complaint is the oil. Hope you can help me out!

How much should I take per day? Do I start with a low dosage & work myself up to a larger dosage?

Do you have to keep taking it forever, or can you eventually stop taking it?

Should I take a pill that has just B5, or can I take a B complex that has B5 in it - is there a difference in effectiveness?

What are possible side effects I could experience?

Also, I saw some mention of saw palmetto... is that something that could also help oily skin?
